look awsome, reminds me of a sculpture i saw a few years ago, had the same effect excepti tkept burning pidgeons as they flew through the focal point o the light lol

i love this post. it is funny. ha. ha.

Woah prosthetic hot dog sticks! Hi-tech!

It is actually possible to make a much smaller and cheaper, but still effective, version of this to cook hotdogs (or anything, really). Can be useful when you're camping or just bored:
1.Thoroughly gluestick aluminum foil to a paper plate
2.Make about a dozen cuts from the rim towards the center, stopping about 2 inches from the center.
3.Overlap the flaps and staple into a bowl or cone (The deeper the depression, the more focused the energy)
4.Secure a stick or wire through the middle to hold the hot dog, so it pokes out like the arm on a satellite dish, and mount the whole thing in a cardboard box, pointed at the sun.
5.Leave it for a few hours to cook, but not too long as this device can scorch your food!
(Cooking times will vary.)

Not that easy to bring to a bbq in the park but very cool.

Here's a similar dish, that could do a lot more than cooking. :)

actually, all the curvature does is determine where the focus of the mirror is. All concave mirrors have a focus at a determinable point when using the sun as your light source
